AUTOMOBILE HEADLI'GHT mm m 19285,. lsm

Filed Feb. 9, 1925 A f3 Sheets-Sneek 3 lam gives a limited lateral distribution of the eam of light and the prismatic portion in addition to giving a limited amount of lateral distribution also causes a still further bending down of the rays of light which pass through the upper portion of the lens.

Having thus described my invention, what I claim is:

l. In a light projector, the combination with a reflector, of a lamp having two independently lighted filaments, one of said filaments being slightly below the axis of the reflector and the other one slightly above said axis, the upper half of the reflector being in the form of a parabola, the rear portion of the lower half of reflector being also a parabola, the forward -portion ofrthe lower half being carried below and outside the normal curvature of revolution whereby the rays of light from either filament will be directed downwardly, and transition surfaces arranged between the upper and lower halves of the reflector.

2. In a light projector, the combination with a reflector, of a lamp having two independently lighted filaments, one of said filaments being slightly below the axis of the refiector and the other one slightly above said axis, the upper half of the reflector being in the form of a parabola, the rear portion of the lower half of reflector being also a parabola, the forward portion of the lower half being carried below and outside the normal curvature of revolution whereby the rays of light from either filament will be directed downwardly, transition surfaces arranged between the upper und lower halves of the reflector, and a lens arranged in advance of said reflector, the major portion of said lens having flutes for causing lateral distribution `of light, the extreme upper portion of said lens having flutes', said upper flutes being prismatic and thickest at their lower ends whereby rays of light reflected romthe forward portion of the upper half of reliector are refracted downwardly.

In testimony whereof, I hereunto ailix my signature.
